 Abstract-Adsorption properties of Georgian expanded perlite prepared on the basis of perlitenatural mineral of Georgia in the process of aqueous solution purification from bivalent iron ionswere investigated for the first time in the work. The dependences of adsorption degree and volume capacity on change of solution pH, adsorbent dosage, contact time and adsorbate concentration were studied. Tests were mainly conductedunder dynamic and static conditions. Optimum conditions for Fe2+
